Abstract

A traveling reactor power monitoring system includes a traveling reactor power monitoring system including a drive control unit configured to move a traveling probe in a guide tube by rotating a motor, and a proximity switch that generates a I stpreventing retraction signal when the travelling probe is detected by the proximity switch to exist at a predefined stop range in a shielding vessel. The drive control unit stops retracting the travelling probe when the 1 stpreventing retraction signal is generated by the proximity switch, and wipes out the 1 stpreventing retraction signal by detecting that the probe exists outside the predefined stop range on the basis of a probe information as a substitute for the 1 st preventing retracting signal output by the proximity switch.
